Re: RPG 500 SIP settings

Hello,

i know this,i have an issue with RPG 500 behind a juniper firewall,while H323 is operational,there is no SIP incoming and outgoing at all.

I tried to reproduce this scenario but behind sophos UTM and i can see that outgoing is OK but i can not receive incoming,call is not establish,maybe sip signaling is mulfunctioning,that's why i would like to change this port.

Re: RPG 500 SIP settings

But the Group is successfully registered to SIP-Server/Registrar? What Software version is installed on Group? If you want to troubleshoot, start with Wireshark and check what SIP error message you receive.

Re: RPG 500 SIP settings

i have traced the port,it seems that Polycom sends his internal IP to contact header,i think it should send its public,to be like 100.100.10.100:5060 but now it send 192.168.1.10:5060,so the other settings does not know where to respond.

With exactly the same firewall settings,i replaced Polycom with a video conference of another vendor,with the same internal ip,same public NAT and it worked.

Maybe it is a bug for 6.1.7-6.1.8 version,i will downgrade to test 6.1.5

Re: RPG 500 SIP settings

Yes of course!! You always need an SIP-Server for communication! If you want direct communication, use H.323. I think you should read a bit about the topic VoIP, then it gets clearer for you to understand.
